JOSEPH E. MORSE, OF SPRINGFIELD, VERMONT.

LIFTING-J'ACK.

Specification of Letters Patent.

Application filed July 19, 1909.

Patented Feb. 8, 1910.

Serial No. 508,287.

To all whom it may concern:

Be it known that I, Josnrn E. Monsn, a citizen of the United States,residing at Springfield, in the county of Vindsor and State of Vermont,have invented certain new and useful Improvements in Lifting- Jacks; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to jacks for raising vehicles and the objectthereof is to provide a simply constructed, strong and efficient deviceof this character for raising the wheels or axles of vehicles and isespecially designed for automobiles to relieve the tires of the weightof the machine when the car is standing in garage one of the jacks beingplaced to support each wheel.

With this and other objects in view, the

invention consists of certain novel features of construction,combination and arrangement of parts as will be more fully described andparticularly pointed out in the appended claim. k In the accompanyingdrawings; Figure 1 represents a side elevation of this improved liftingjack; Fig. 2 represents an end view thereof; and, Fig. 3 is a transversesection taken on the line 33 of Fig. 1.

In the embodiment illustrated an upright supporting member 1 is showncomposed of two laterally spaced bars 2 and 3 of any suitable materialand of any desired width and thickness. An axle engaging member l ismounted between the upper ends of the bars 2 and 3 and is secured inposition by means of bolts 5 and (3 which extend through transverselyspaced slots 7 and 8 which are arranged longitudinally of the side bars2 and 3 and are designed to permit the vertical adjustment of the memberA to adapt the ack to fit vehicles having axles disposed differentheights from the ground or other supporting surface. The upper end ofthe member 4 is preferably cut out to form a rounded recess 9 to receivethe axle and hold it against lateral movement. A lever 10 has one endthereof disposed between the bars 2 and 3 and extends laterally at rightangles thereto and the upper edge of said lever preferably abuts againstthe lower end of the member l. This lever 10 is secured to the bars 2and 3 by means of a bolt 11 which extends through registering slots as12 arranged longitudinally in the side bars :2 and 3 and which providefor the vertical adjustment of said lever to correspond with theadjustment of the member 4 whereby the upper edge of the lever is alwaysheld in abutting engagement with the lower end of the member 4. Braces13 and 14 are connected at one end to the upper end of the member 4 onopposite sides thereof as is clearly shown in Fig. 2 and at their otherend to the lever 10 at a point about midway the length thereof, saidlever being arranged between said braces. A wheel or roller 15 isrevolubly mounted between the lower ends of the bars 2 and 3 with theperiphery thereof projecting slightly below said ends to provide for theready movement of the ack over the ground or other supporting surface.The main portion of the wheel is arranged between the bars 2 and 3 andis braced thereby and all danger of the wheel bending latorally orbreaking under a heavy weight is avoided. The member A and the lever 10serve as spacing blocks for the bars 2 and 3 and prevent all danger ofbinding of the wheel thereby insuring its ready revolution at all times.

In the operation of this jack when the vehicle is to be lifted the freeouter end of the handle or lever 1.0 is raised thereby lowering the freeend of the member at until the recess 9 therein is engaged with the axleor hub of the wheel to be supported. The handle is then pressed downinto the position shown in Fig. 1 forcing the wheel carried by themember a upward out of contact with the supporting surface. It will beobvious that one of these jacks is to be used to support each wheel of amachine and they are constructed as above described to provide thenecessary strength for supporting vehicles of the character for whichthey are designed.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claim.

I claim as my invention;

A lifting jack comprising two laterally spaced side members having awheel rotatably mounted between the lower ends thereof, an axle engagingmember disposed be tween said bars with its upper end projectingthereabove and provided with an axle engaging recess, longitudinallyextending registering slots arranged in said side bars, bolts extendingthrough said axle supporting member and through the slots in said sidebars, a lever having one end arranged between said side bars with itsupper edge abutting the lower end of said axle supporting member, a boltextending through said lever and through two of the registering slots insaid side bars and brace bars connected at one end to the upper end ofsaid axle engaging member on opposite sides thereof and at their otherends to the lever on opposite sides thereof.

In testimony whereof I have hereunto set 20 my hand in presence of twosubscribing wit-
